I was considering composting the grounds and looking at one web site that says mix 4 parts brown material to 1 part green (coffee grounds) .......another says to mix equal parts brown and green. One says coffee grounds are very acidic and the other says they can vary from slightly alkaline to slightly acidic.
One web site says that a good option is to spread about an inch over an an area then till into soil and that the grounds do a good job of conditioning the soil and break down slowly. Another says never spread grounds in garden they are way to acidic and must be composted first.
Right now the coffee grounds are going into trash. and is just a short distance from me.
I am thinking of taking them and dumping into a pile, then spread it and till it in in the spring.
